Heat Dump Valve; Pre-Start Inspection Procedures - Mi-T-M HHS Serie Manual Del Usuario

InstallatIon & PRePaRatIon

Heat dumP ValVe:

To ensure the water temperature does not exceed acceptable levels, never allow
the pressure washer to operate in the bypass mode (with the unit running and
the trigger closed) for more than five minutes.
A "heat dump valve" has been added to this unit to protect the pump. This valve
will open and release water if the water temperature in the pump has exceeded
40° F. This will allow fresh, cool water to enter the system, therefore preventing
premature failure of pump packings.

PRe-staRt InsPectIon PRoceduRes:

Before starting the unit, perform the following procedures:
. Inspect the electrical cords for cuts. If a cut is found, DO NOT TOUCH OR
USE CORD! Replace cord before starting unit.
2. Check the oil level in the pump.
3. Inspect the water inlet strainer. Clean or replace if necessary. See "Water
Supply", #2, pg 2.
4. Check all hose connections to ensure they are securely tightened.
5. Inspect for system water leaks, oil leaks and fuel leaks. If a fuel leak is
found, DO NOT START UNIT! See "Risk of Explosion or Fire", pg. 5. Be
sure that all damaged parts are replaced and that the mechanical problems
are corrected prior to operation of the unit. If you require service, contact
Customer Service.
6. Inspect high pressure hoses for kinking, cuts and leaks. If a cut or leak
is found, DO NOT USE HOSE! Replace hose before starting unit. See
"Risk of Injection or Severe Cutting Injury", pg. 6. Be sure that all damaged
parts are replaced and that the mechanical problems are corrected prior to
operation of the unit. If you require service, contact Customer Service.
